Late Flowering Expression

Late flowering expression refers to the delayed or extended production of aromatic terpenes during a cannabis plant's final growth stages, particularly in the final 2-4 weeks before harvest. Rather than a single terpene, this describes a phenological pattern where volatile compounds accumulate, shift, or become more pronounced as flowers mature. Lineage records frequently report this trait in certain cultivar families, especially those with extended Indica or extended photoperiod genetics. The timing and intensity of late terpene expression can vary significantly between individual plants within the same strain, influenced by environmental factors, light cycles, and nutrient availability. Understanding this pattern is important for breeders selecting for specific aromatic profiles at harvest.

Breeders working in this category often select parent plants that reliably exhibit robust terpene development in final flowering stages, as this trait can enhance complexity and shelf-stable aroma. Stabilizing late flowering expression through multi-generational selection helps create consistent end-product profiles across commercial seed lines.
